Optimal Conditions

Product Introduction

Refining enzyme facilitates the removal of P (primary wall) and S1 (outer layer of secondary wall) through mechanical action, thereby reducing beating current and achieving the goal of lowering beating energy consumption.

Features

• Reduce refining energy consumption by more than 10%

• Reduce long-fiber pulp ratio by 5-15%

• Extend the service life of refiner plates, save costs, and increase pulp yield

• Enhance inter-fiber bonding and improve paper strength

• Demonstration of comprehensive benefits

Precautions

• The specific dosage of this product is determined by the pulp composition, treatment temperature, pH, and reaction time.

• It can be added at a position before the refining stage that allows for a retention time of approximately 20-60 minutes.

• During use, the temperature and pH must be maintained within the optimal range; otherwise, the enzyme activity will significantly decrease.
